Singer Janet Jackson has recorded a new video for amfAR, the nonprofit started by the late Elizabeth Taylor dedicated to the support of AIDS research, HIV prevention, treatment education and public policy.

In the 30-second video released on World AIDS Day, Jackson reminds viewers that AIDS is not over.

“More than a million Americans are living with HIV. And one in five of them don't even know they are infected,” Jackson says. “So please get tested.”

“And if you're HIV-positive, get treated. Support the research, it's our only hope in finding a cure.”

“Let's end AIDS together,” she adds. (The video is embedded on this page. Visit our video library for more videos.)

The 46-year-old Jackson also joined amfAR's Mathilde Krim, Ph.D. in penning a CNN op-ed.

“While the AIDS research and activist communities continue to celebrate some major breakthroughs during the past few years, we continue to struggle with an epidemic in the United States that grows unabated,” they wrote.

“And while everyone is at risk and should know their status, data tell us that communities of color – particularly black women and young, black gay, bisexual and other men who have sex with men – are disproportionately affected by the virus. If we're going to create an AIDS-free generation here at home, we need to start investing in resources that will curb the epidemic among these populations.”
